Abstract (en)

[origin: WO2009053206A1] The invention relates to a register charging unit for compressing charge air supplied to an internal combustion engine, having a first register stage comprising a first compressor, having a second register stage comprising a second compressor, wherein charge air can be applied to the first compressor and the second compressor in parallel via a charge air line, having a bypass line that creates an air-conveying connection between a downstream branch point behind the first compressor to an upstream supply point in front of the second compressor, wherein a compressor sequence valve is disposed in the region of the supply point in the charge air line for opening and closing both the charge air line and the bypass line. The invention further relates to a compressor sequence valve having a housing, comprising a first inlet region, a second inlet region, and an outlet region that is connected to the first inlet region and the second inlet region in a flow-conducting manner, wherein a first sealing element for opening and/or closing of the first inlet region is operatively connected to a second sealing element for opening and/or closing the second inlet region such that an opening of the first sealing element brings about a seal by the second sealing element, for use in a register charging unit.
